Recent insights for the green recovery of inulin from plant food materials using non-conventional extraction technologies: A review
2016
Abstract Inulin constitutes an important food ingredient, widely used for its fiber content, and its ability to substitute fat and sugar ingredients. Traditionally, industrial inulin production from chicory roots requires high extraction temperature (70–80 °C) and long extraction time (1–2 h). This conventional extraction is generally accompanied with the presence of a large amount of impurities in the extracted juice, mainly due to the application of high temperature, requiring thus further purification steps. To overcome these issues, developing novel extraction technologies, consuming less energy, faster, and providing high yield and purity, is of paramount importance to meet the require…
Intensity invariant nonlinear correlation filtering in spatially disjoint noise.
2010
We analyze the performance of a nonlinear correlation called the Locally Adaptive Contrast Invariant Filter in the presence of spatially disjoint noise under the peak-to-sidelobe ratio (PSR) metric. We show that the PSR using the nonlinear correlation improves as the disjoint noise intensity increases, whereas, for common linear filtering, it goes to zero. Experimental results as well as comparisons with a classical matched filter are given.
Modified morphological correlation based on bit-map representations.
1999
Pattern recognition with high discrimination can be achieved with a morphological correlator. A modification of this correlator is carried out by use of a binary slicing process instead of linear thresholding. Although the obtained correlation result is not identical to the conventional morphological correlation, it requires fewer calculations and provides even higher discrimination. Two optical experimental implementations of this modified morphological correlator as well as some experimental results are shown.
Probabilistic models for the fatigue resistance of welded steel joints subjected to constant amplitude loading
2022
Abstract S-N curves found in various rules and regulations are the basic tool for the practicing engineer when carrying out life predictions for welded details in dynamically loaded structures. The present work is investigating the expected fatigue life and associated scatter for welded steel joints subjected to Constant Amplitude (CA) loading. The objective is to obtain more reliable life predictions based on advancements in the probabilistic model fitted to collected life data. A Random Fatigue Limit Model (RFLM) is proposed to obtain fatigue resistance curves at given probability levels of survival. As a distinction to more conventional statistical methods, the model is treating both the…
Trace compounds of biogas from different biogas production plants
2007
Biogas composition and variation in three different biogas production plants were studied to provide information pertaining to its potential use as biofuel. Methane, carbon dioxide, oxygen, nitrogen, volatile organic compounds (VOCs) and sulphur compounds were measured in samples of biogases from a landfill, sewage treatment plant sludge digester and farm biogas plant. Methane content ranged from 48% to 65%, carbon dioxide from 36% to 41% and nitrogen from <1% to 17%. Oxygen content in all three gases was <1%. The highest methane content occurred in the gas from the sewage digester while the lowest methane and highest nitrogen contents were found in the landfill gas during winter. The amoun…
Fractional-Fourier-transform calculation through the fast-Fourier-transform algorithm.
1996
A method for the calculation of the fractional Fourier transform (FRT) by means of the fast Fourier transform (FFT) algorithm is presented. The process involves mainly two FFT’s in cascade; thus the process has the same complexity as this algorithm. The method is valid for fractional orders varying from −1 to 1. Scaling factors for the FRT and Fresnel diffraction when calculated through the FFT are discussed.
Spatial dispersion intensity measure of phase concentration distributions and its applications to quantitative characterization, distinguishing and c…
2008
A method of evaluation of spatial dispersion of structures is presented. A quantitative parameter measuring spatial dispersion is introduced. It is shown that this parameter indeed measures spatial dispersion. A classification of bubble flow structures based on values of this parameter is proposed. An example of application of the method to real flow structures is presented.
The Diffusion of the Activity-Based Costing Method: A Comparison between France and China
2011
In France, like in the USA, the Activity-based Costing method (ABC) was considered as a remedy for the crisis of management accounting. Now, the level of diffusion in France is as important as in the Anglo-Saxon countries. Not surprisingly, the ABC method is more developed in western countries than in China. Chinese scholars began to do researches on ABC in the 1990s and at the beginnings of the 21st century, we can observe some ABC implementations in Chinese manufacturing enterprises and then in the service industries. But, we can also find a similarity between the Chinese and French situations. In France, we have observed some resistances to the Anglo-Saxon way of manage firms and at the …
In-house versus external basic research and first-to-market innovations
2016
This paper explores to what extent conducting internal basic research, as opposed to external basic research (i.e. outsourcing and collaboration with universities) encourages firms to bring new products into the market ahead of competitors, and contributes to innovation performance. The analysis is based on a sample of Spanish manufacturing firms over the period 2006–2012. Our findings suggest that conducting in-house basic research affects firm's propensity to introduce product novelties. Furthermore, performing this activity continuously affects the probability of being product-pioneer in low and medium–low tech sectors. Collaboration with universities also helps in introducing new produc…
Event‐brand transfer in an entertainment service: experiential marketing
2013
PurposeOne of the channels a brand can use to create experiences is events. The brand promoting the event and its sponsors can obtain various benefits in the form of brand image, personality and notoriety. The main aim of this research is to evaluate the effects that experiencing an event has on experience with the promoting brand.Design/methodology/approachThe study analysed the musical event MTV Winter Festival 2010, considering the opinion of 127 attendees to discover the impact of experiencing the MTV entertainment television channel event in three areas: improved brand experience, improved brand personality and increased brand reputation. EQS was used to test the proposed model.Finding…
